JOSEPH B. WATKINS, OF WILLOW SPRINGS, MISSOURI, ASSIGNOR OF ONE-HALF TO ROYAL D. ROSIER, OF WILLOW SIINGS, MISSOURI.

OIL BURNER.

Application med February 23, 1922.

T o all whom t may concern Be it known that JOSEPH B. VVATKINS, a citizen of the United States, residing at Willow Springs, in the county of Howell and State of Missouri, has invented certain new and useful Improvements in Oil Burners, of which the following is a specification. This invention has relation to certain new j and useful improvements in an oil burner adapted for stoves, ranges and the like and has for its primary object the provision of a burner of this charac-ter which will be of extremely simple construction, formed in such a manner that the parts thereof may be connected readily and the burner proper adjusted automatically so as to cause the proper operation of the burner.

The invention has for another object the provision of an oil burner of the character stated in which the oil will vaporize before passing to the burner proper and `then consumed at the nozzle of the burner proper so that the heat from the burner proper will be directed to the vaporizing chamber to cause vaporization of the oil passing through the same on its way to the burner proper. The invention has for a further object the provision of an oil burner of the character set forth which may be composed of especially formed pipe sections and connections together with a valve member and valve mechanism and a vaporizing chamber, all of the parts beingof simple construction and arrangement and of such form that they may be readily connected or disconnected,

as desired.

The invention has for a still further object the .provision of an oil burner especially Y of the character stated which will be of inexpensive construction, highly efficient in use and may be adapted to stoves of various types and wherever a burner of the character of the present invention may be empleyed.-

W'th the foregoing and other objects in Viewl as 'will appear as the description proceeds, the invention consists in the novel construction, combination and arrangement of co-operating elements as hereinafter more specifically set forth, claimed and shown in the accompanying drawings forminga-part of the present application and in which Figure 1 is an elevation of the improved form of burner.

Figure 2 is a longitudinal vertical section.

through the burner section with the vaporizing chamber shown in elevation.

Referring more in detail to the drawings in which similar reference characters designate corresponding parts throughout the several views, 1 indicates the oil supply pipe which has a threaded free end 2 for connectlon with a suitable source of oil supply, not shown. The opposite end of the pipe 1 connects with a section 3 of the pipe through which the valve stem 4 is extended. The pipe section 3 is extended at right angle to the portion of the pipe l connecting therewith and in a plane parallel with the main portion of the pipe l, as will be readily understood vby referring to the drawings- One end of the pipe 3 is closed by a plug 5 threaded therein and within which the hearing or packing member 6 is threaded. The valve stern 4 extends through the registering central passages of the plug 5 and bearing or packing 6. The valve stem 4 is operated by the head or knob 7' having a roughened edge, as shown in Figs. 1 and 2. The remaining end of the pipe section 3 is threaded in one end of the T-coupling 8 while the pipe section 9 is threaded in the opposite end of the T-'coupling 8 so as to extend in alinement with the pipe section 9. The burner proper 10 is threaded in the remaining or free end of the pipe section 9 and the burner'nozzle 11 is extended upwardly from the burner proper 10. The valve stem 4 has its free end extending into the burner proper 10 after the stern 4 passes through the connecting tube 8 and the pipe section 9. This free or inner end of 'the valve stem 4 operates against the pivoted valve member 12. This valve member 12 lis pivotally mounted in the burner proper '12 and has a needle or pointed member 13 on one arm adapted to be forced upwardly into the burner nozzle 11 as the valve stem 4 is forced inwardly. This valve member 12 is ofA substantially right-angle constri`ic tion and tends to normally swing downwardly from the burner nozzle Il on the pivot member of the member 12 when the valve stem 4 is swung outwardly, as will be clearly understood by referring to the drawings.

The pipe section 9 has a flange member 14 extended therefrom and positioned parallel with the pipe section 9 to receive the coupling member 15 of the nearest conducting pipe 16. This coupling member 15 is carried on one end of the gas pipe 16, the remaining end of which connects With one end of the vaporizing chamber 17. The opposite end of the vaporizing chamber 17 is connected With one end of the oil conducting pipe 18 which extends from the stem of the T- coupling 8, previously mentioned. It Will be understood that both ends of the oil conducting pipe 18 are preferably threaded and it will also be seen by referring to FiOs. 1 and 2 that the vaporizing chamber 17 is of substantially elongated or provided with int'eriorly threaded extended end portions to receive respectively the ends of the oil con ducting pipe 18 and the gas conducting pipe 16. It Will be seen that by the arrangement described, the pipes 16 and 18 are curved or i bent so as to position the vaporizing chamber 17 immediately above and a suitable space from the burner member 10. This will result in the heat from the burner serving to vaporize the oil passing through the oil pipe, the `pipe section 3, the T-connection 8 and the oil conducting pipe 18 into the vaporizing chamber 17. The fuel, then, during operation of the burner will pass out of the vaporizing` chamber 17 in the form of vapor and travel through the gas conducting pipe 16. through the branch 14 of the pipe section9 and into the burner member 10, from which it may be consumed at the burner nozzle 11, the flow of the fuel out of the burner member 10 and through the nozzle 11 being controlled by proper position or regulation of the Valve member 12. It is to be understood that When the operation of the burner is to be started, a sufficient amount of the oil mustbe permitted to pass through the vaporiz'ing chamber 17 and through the gas conducting pipe 16 to the burner member 10. As soon as operation of the burner is started, however, the vaporizing of the fuel will. be caused in the vaporizing chamber 17 as to supply the fuel in gaseous form to the burner nozzle 11. It is believed that further detailed description of the construction and operation of this simple form of burner will be unnecessary as the complete device should be understood from the foregoing paragraphs taken in connection withthe accompanying drawings.

While the preferred embodiment of the invention has been shown and described. it is to be understood that minor changes in the details of construction and arrangement 'ing pipe, a supply pipe connected With said main conducting pipe, a branch pipe connected with said main pipe, a burner member mounted on one end of said main pipe, a valve stem Working through the opposite end of saidmain pipe, a valve member' pivoted in said burner member, said burner member having a burner nozzle projecting therefrom, a vaporizing chamber mounted on said branch pipe, above said burner nozzle, said valve stem being adapted to control said valve member to regulate the flame of the burner and a shaft conducting pipe extended from Said vaporizing member to said main pipe at a point adjacent said bottom member.

2. A burner comprising a main pipe, a burner member mounted on one end of said main pipe, a valve stem operating through said main pipe and projecting from the remaining end thereoi, an oil supply pipe connected with said main pipe, a vaporizing member positioned above said burner mem ber, an oil conducting pipe extending from said main pipe to said vaporizing member to said main pipe to carry a gaseous fuel to said burner member, said burner member being located beneath said vaporizing member, and a controlling valve for said burner member mounted in the latter and controlled by said valve stem.

3. A burner comprising an elongated vaporizing chamber, pipes extending' from the reduced opposite end of said chamber, a main conducting pipe, an oil supply pipe connected With said. main supply pipe near one end. thereof, one of the pipes from said vaporizing chamber beingconnected with the central portion of' sa id main conducting pipe, a burner member mounted on one end of said main conducting` pipe between said vaporizing chamber, the remaining pipe extended from said vaporizing chamber bei ng turned and connected with said main conducting pipe near the end carrying the burnermember. a valve member pivotally mounted in saidburner member, and a valve stem extending through said main conducting pipe and projecting from one end there oiilto control said pivoted valve member.
